Specification of Letters Patent.

Patented Feb. 2S, 191i.

Application filed February 19, 1910. Serial No. 544,824.

Britain and lreland, residing at 33 Colne l 5 road, Twickenham, in the county of Middlesex, England, have invented certain new and useful lmprovements in Non-Refillable Bottles; and l do hereby declare the following to be a full, clear, and exact description such as will enable others skilled in the art to which it appertains to make and use the same, reference being` had to the accompanying drawings, and to letters or figures of reference inaiked thereon,

l5 which form a part of this specification.

This invention relates to non-refillable bottles of the type in which a chambered stopper is inserted in the neck of the bottle, the said stopper being provided with orifices or passages permitting the outflow of liquid but controlled by and the infiow of air,

inflow of liquid means which prevent the and outflow of air.

The ob]ect of the present invention is to dispense with the valves usually employed for controlling the air inlet passage and to provide a device for this purpose which is not dependent upon gravity for its operation and is of suoli a nature as to prevent the inflow of liquid even if suction is applied to the bottle.

Other objects are to which can be very easily provide a stopper inserted in the bottle neck and locked therein so that it cannot be removed therefrom without necessitating fracture of the bottle neck, but which when removed from a fractured bottle can be used again in another bottle.

rlhe invention consists in providing with- 40 in the air passage a diaphragm of material which will permit the passage of air, but is impervious to liquid.

rlhe invention also consists in so arrang ing the aforesaid diaphragm in the air passage that an air lock is formed on one side of it and a liquid seal on the other side, if any attempt is made to insert liquid into the bottle.

The invention further comprises various 'details in combination forming the improved stopperhereinafter particularly referred to.

Figure l is a sectional elevation of part of a bottle fitted with one form of stopper invention. Fig. 2 is a 3 is .a sectional elevation, showing the stoppei' in elevation as viewed from a direction perpendicular to the plane of section of Fig. Fig. t is a cross section on the line Il., ll., Fig. 1. Fig. 5 is a perspective view of a locking device. Fig. G is a similar view to Fig. 8 but illustrating the application of the stopper' to a bottle of different form. Figs. 7 and 8 are detail views illustrating packing rings which may be used.

ln carrying out the invention according to one form, as illustrated by way of eX- ample in. Figs. l to 3, the stopper comprises two portions a, o, made of porcelain or other material not likely to contaminate the contents of the bottle. rlhe portions a, I), are screwed or otherwise firmly secured together and are prevented from moving relatively, by a pin c. The lower portion a, is divided by a partition cl, so as to form a liquid outflow passage c, and an air inlet passage which is subdivided by a diaphragm j', into two chambers g, 7L. The liquid outflow passage e, communicates by a lower orifice t', with the interior of the bottle 7c, and by a lateral orifice Z, with an annular space m, between the neck of the bottle 7c, and the stopper. The lower orifice z', is controlled by a check valve n, which preferably consists of a thin disk of mica held at one side by a pin 0.

The chamber z., communicates with the interior of the bottle by an air tube ya; while the chamber g, communicates with the annular space m, by a lateral orifice g.

The diaphragm y, may be held between frames s, s, of wood, vulcanite or similar material. It is of such a natui'e that it will permit the passage of air, but will resist the passage of liquid. For example, it may be of fabric preferably iendered waterproof, but not air-proof, as is well-known in the arty of clothing manufacture. It may be of fine gauze or a finely perforated plate similarly treated; or it may consist of a very porous earthenware porcelain or like disk.

The lower part a, of the stopper rests on a ledge r, formed in the neck of the bottle. Another ledge s', prevents the insertion of a wire for the purpose of tampering with the valve n, and it also forms an abutment for one part t, of an elastic locking device a, the other part o, of which. abuts against the ledge formed by the lower edge of the portion o, of the stopper, as indicated in terfere with the insertion of the stopper, but when the latter is arrested by the ledge r, the part 25, of the device fu, springs out and engages with the ledge s.

A cork lining w, or other packing is preferably provided between the two portions a, and Z), of the stopper and a packing ring 6, Fig. 7 may be provided between the lower portion a, of the stopper and the ledge r. A cork ring 7, Figs. 7 and 8 may be provided around the stopper, openings 8 and 9 being cut in it to correspond with the orifices Z and g in the stopper.

1n order to avoid the injury to the valve ln, and to the diaphragm j', should a force pump be applied to the bottle, safety disks fe, and y, are provided. They are loosely fitted in their chambers so as not to interfere with the normal operation of the valve a, and diaphragm, but merely to act as guards therefor against sudden and abnormal pressure from outside. The guard y, may have a bleed hole 5 for air.

The bottle neck may be closed by an outer cork e, and a seal 2 of wax or other material.

The upper rim 3 of the stopper may fit the neck of the bottle so as to prevent lateral movement, holes 4, Fig. et, being formed to permit outflow of liquid and inflow of air.

Then it is desired to pour out liquid from the bottle, the seal 2 and cork s, are removed, and the bottle is tilted. Air enters through the orifice g, chambers g, and 7L, and tube 29,' and liquid flows out through the orifice z', chamber E and orifice Z.

Any attempt to insert liquid simply results in flooding of the chamber g, which thereby acts as a liquid seal, while the chamber it, and tube 79, act as an air lock. As the diaphragm f, will not permit the passage of liquid, any attempt to draw in liquid via the air passage, by suction applied to the liquid passage is frustrated.

Having thus described my invention what l desire to secure by Letters Patent is 1. In combination a bottle, a stopper arranged within the neck of the bottle so as to leave an annular space between the stopper and the bottle neck, the aforesaid stopper having a liquid outflow passage and an air inlet passage, each passage communicating with the aforesaid annular space and the interior of the bottle by lateral and lower orifices respectively, a check valve for the lower orifice of the liquid passage and a diaphragm for subdividing the air passage, said diaphragm being of a material impervious to liquid but not to air, substantially as and for the purpose hereinbefore set forth. l

2.
